    12th Gen Intel Core i7 1255U | Review

    12th Gen Intel Core i7 1255U ReviewLaunched in January of 2022, 12th Gen Intel Core i7 1255U is a high-end processor for laptops powered by 2 performance cores with 4 threads and 8 efficiency cores with 8 threads. The performance core has a base clock of 1.7 GHz and a boost clock of 4.7 GHz the efficiency cores, on the other hand, have a base clock of 1.2GHz and a boost clock of 3.5GHz. 12th Gen Intel Core i7 1255U is based on the 10 nm architecture with this the 12th Gen CPUs see an average IPC gain of 19 percent the higher IPC allows the Alder lake CPUs more performance at the same clock speed. The TDP of this Chip as specified by intel is 15 watts and can go up to 55 Watts. It also has support for new faster DDR5 memory of up to  4800MHz and low power LPDDR5 5200MHz while also supporting DDR4 memory of up to 3200MHz and low power LPDDR4X 4267MHz. Other Key Features Include Intel Iris Xe Graphics 80EUs and support for USB 4 (40Gbps).
